EPECIFICA'IION forming part of Letters Patent N 0. 446,597, dated February 17, 1891. Application filed December 26, 1889, Serial No. 384,996. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES J. HARTLEY, of the city of Decatur, county of Macon, and State of Illinois, have invented certain new and useful Improvements in Conveyors, of

which the following is a specification.

My invention is designed to coact with the elevator and weigher of a thrashing-machine;

. and it consists in the details of construction I0 and combinations of parts hereinafter set forth and claimed, whereby pivotal adjustment in different directions may be easily had without complicating or interfering with the action of the motive mechanism. is In the drawings accompanying and forming a part of this specification, Figure l is an end view of my device, showing, generally, its relation to an elevator and weigher; and Fig. 2 is a side view of the conveyor detached :0 from its support and minus its actuatingchain. The hopper a opens into the conveyor I), which is provided with a rotating spiral, that advances the contents of the conveyor. Vertical bearing an is supported by bars or rods 72 and 0 and by additional braces, if desired. The pin f pivots in bearing m, and it carries the conveyer rest g and the horizontal arms h. Arms 7i are secured to the hopper, and 0 they pivot on rod or shaft 2', which is supported by arms h. A sprocket-wheel Z is mounted on pinf and connected with a chainwheel 6. Idlers dare mounted on shaft '5, and wheel 0 is fixed on the shaft of the spiral of 3 5 conveyor b. Chain 1 extends around wheels 0, (Z, and aand conveys motion from sprocketwheel Zto the spiral of theconveyer. A wheel 8 is actuated by the thrasher, and its motion is imparted to wheell by link belt r. The

0 link belt makes a quarter-turn, and it is supported interniediately by idlers p and q, the latter of which is adapted to act as a tightencr zontal adjustment, the swinging end of the conveyer may be raised over the same and again lowered into contact with the rest.

The chain and sprocket wheels impart power unyieldingly; but where this peculiarity is not desired other forms of belt will provide the essential thing-a flexible power-transmitter-quite as well.

I claim as new and desire to secure by Letters Patent 1. In conveyors, the combination of the conveyer-pipe having a revoluble spiral, the

driven wheel on the shaft of the spiral, the pivot-pin supporting the conveyer-pipes, the drive-wheel on the pin, the idlers, and the link belt connecting the wheel on the pin with the wheel on the conveyer-shaft, as set forth.

2. In conveyers, the combination of pivotpin f, having rest g and arms h, conveyer b, having the revoluble spiral and connecting pivotally with arms h, wheel 0 on the conveyer-shaft, idlers d, wheel 6 on the pin, and link belt r, connecting the wheel of the pin with the wheel of the conveyer-shaft, as set forth.

In testimony whereof I sign my name in the presence of two subscribing witnesses.

CHARLES J. HARTLEY.
